研究了一种由氟塑料、石墨和二硫化钼组成的AФГM新材料,用以制造压缩机活塞环。正如AФГM材料在试验室条件和无润滑压缩机运转条件下的磨损试验表明,该材料在干燥惰性气体介质中使用时,具有较高的耐磨性。压缩干燥空气和氧气时,这种材料的耐磨性有所降低。但是表示AФГM材料耐磨性的绝对值仍然是较小的,从而可将其成功地应用于压缩上述气体的压缩机中＊。研究过程中,对AФГM材料在所探讨介质中工作时耐磨性降低的原因的确定,也令人
A new material, AФГM, consisting of fluoroplastic, graphite and molybdenum disulfide was developed for the manufacture of compressor piston rings. Just as wear tests of AФГM materials under laboratory and non-lubricated compressor conditions show that the material has high wear resistance when used in a dry inert gas medium. When compressed dry air and oxygen, the wear resistance of this material is reduced. However, the absolute value of wear resistance of the AФM material is still small, so that it can be successfully used in compressors that compress the above gases. In the course of the study, the determination of the reason for the reduced wear resistance of AФГM materials when working in the medium in question was also made
